      Great harness that works perfectly when upgrading your truck to a Sync 3 8” screen and APIM. One thing to note, there are several similar harnesses available but beware that they don’t all come with the video connection, some leave it out and require you to purchase an additional adapter. This harness includes everything as well as fantastic support that you definitely don’t find elsewhere. You won’t be left hanging. I definitely recommend buying here.
